STEAM HEATED SADIRON Filed Aug. 20, 1951' Patented Aug. 30, 1932 UNITEDsrA'rss 11 OFFICE My invention relates to electrically heated irons andthe object of my invention 1s to provide an electrically heated ironwith means for enerating'and superheating steam and releasing the steamthru a plurality of outlets located in the bottom of the iron.

The particular construction of the electrical heating features of aniron is not shown in the present drawing as any of the usual heatersdesigned for the pu ose may be used, but the novel features 0construction relate to the steam superheatin chamber.

Referring to the drawing w ich forms a part of this specification:

Fig. 1 is a perspective view of the iron, illustrating its form andgeneral appearance.

- Fig. 2 is a longitudinal sectional plan view through the steam chamberof the iron.

Fig. 3 is a cross sectional view line 3-3 of Fig. 2.

10 indicates the base portion of the iron which is provided with achamber 11 located in its up er side to receive the heating coil of an eectric heater, carried by the top portion 12.

13 indicates a straight central bore which extends from the butt end 14of the iron to near the point 15 thereof.

16 indicates bores which serve as passages for conducting the steamtothe outlets 1'? drilled in the base 10 in communication with the bores16. The bores 27 respectively, can tend from the end 14 of the iron atan angle to the central bore 13 and intersect the bore 13 near the frontend of the iron to form a chamber 18. Each of the bores is made bydrilling operations, and the ends of the bores 16 and 27 are plugged at19, as shown. The outlet openings 17 are of small diameter and arespaced apart from each other in alignment at predetermined distances.

The valve mechanism 20 and its control levers are described inmy-co-pending application, Ser. 190351 for improvements in sad irons,file October 21, 1930.

The lever 24 controls a valve located in the body 23 which governs theflow of steam from the pipe 25 to the passage 13.

26 indicates a restricted passage on each side of the iron connectingthe passages 16 taken on with the bores 27, the bores 27 being known asthe distributing chamber. The chamber 18 serves as a water: trap and thechambers t2)? serve as super-heating chambers, heated ried in thechamber 11.

It has been found that b theme of the chambers as arranged toget er withthe restricted p1 reaches t e said restricted passages, the flow ofsteam is retarded and all moisture is conthe electrical coils orelectric heaters carassages 26, by the' time the steam verted into steamat a suflicientl high temperature to prevent condensation, as the steamenters the chambers 16 and iiows throu h the outlets 17 at a temperaturecon sidera 1y above 212, whereas prior to the use of said restrictedpassages 26 the steam was not super-heated tov the same degree and theoperation of the iron was therefore not so perfect.

As above constructed, the iron delivers nothing but steam throu h theoutlets 17 and moisture has been entire y eliminated.

Having thus described my invention, I

claim as new 1. An electrically heated sad iron comprisinga base portionhaving a central bore extending from the butt end to near the front endthereof, and having a return here located at each side thereof extendingfrom the central bore to near its butt end, said iron also containin twoouter bores having outlet passages lea ing therefrom, each of saidreturn bores being connected to one of said outer bores by a restrictedpassage.

- 2. The structure as claimed in claim 1, said restricted passage beinglocated about midway between the butt end of the iron and the middleportion thereof.

3. An electrically heated sad iron comprising a base portion have a boreextendin from butt end to near front end thereof an a return bore ateach side thereof extending from said first bore and in opencommunicafront the inner side bores to said outer bores.

4. A and iron comprising a I chamber for an electric heater, sa1d baseportion having a plurality of longitudinally extendin cy mdrical bores,the outer bores having ou et passages for steam and connected with theinner bores by passages of area for the-purpose stated. 5. A sad ironcompns' chamber for an electric portion having an inlet bore; for steamextending from the butt end to near. thefront end of the iron and twoinner bo'res in open communication therewith leading from said front endto the butt end of the. iron; and two outer bores in open communicationat the front end and extending from the front end a base having a to thebutt of the iron and havingrestricted outlet passages for steam, saidlast bores being connected with the inner bores by passages ofrestricted area.

6. An lectrically heated sad iron comprising a base having a boretherein extendmg forwardly from its butt end, a second bore incommunication with said bore, a third bore connected to second bore by ap and outlet passages in said third bore. In testimony whereof Wanna K.Tavnnnm ailixes his si nature.
